Abstract
Double handle knives and attachments to convert a knife to a double handle knife are described with secondary handles able to form an angle (a) between about 20 to 70 degrees between the long axis of the secondary handle and the long axis of the blade in a plane at about right angles to the blade. Embodiments describe fixed, rotatable, and indexable means for the angle of attachment of the secondary handle to the blade. Embodiments further describe reversible and permanent means of attachment. The placement of the secondary handle at the angle described allows for the optimal positioning of the hands for both controlling and assisting with the cutting of foods and other items.
Claims20
1) A fixed-angle handle assembly configured to be supported by a back edge of a cutting blade during a cutting function comprising:
- an upper handle portion having a length longer than its width upon which multiple fingers may be accommodated;
- said length defining a longitudinal axis;
- a lower mounting portion with a slot defining a plane;
- said slot configured to receive the back edge of a cutting blade along the plane of the slot;
- the plane of the slot intersecting the longitudinal axis at a transverse angle of 45 degrees (+ or −25 degree) to the longitudinal axis;
- said traverse angle being in a plane substantially perpendicular to the plane of the slot wherein said transverse angle orients the handle assembly to the back of an installed cutting blade optimally for cutting operations.
10) A double handle knife comprising:
- a cutting blade with a primary handle;
- said blade having a cutting edge and a back edge;
- the blade defining a plane;
- a secondary handle having a length longer than its width upon which multiple fingers may be accommodated;
- said length defining a longitudinal axis;
- means to mount said secondary handle to the back edge of said blade such that the longitudinal axis intersects the plane of the blade at a fixed angle of 45 degrees (+ or −25 degrees);
- said angle being in a plane at about right angles to the plane of the blade, whereby the attachment of said secondary handle to the cutting blade provides an angle optimal for cutting operations.
12) A handle assembly configured to be supported by a back edge of a cutting blade during a cutting function comprising:
- a handle portion having a longitudinal axis sufficiently wide to accommodate multiple fingers and a means for receiving centrally located on the longitudinal axis;
- a second portion having a second axis perpendicular to the longitudinal axis, a top portion, and a bottom portion with a slot configured to receive the back edge of the blade;
- wherein the top portion is received by the means for receiving in a way that allows the handle portion to rotate in a plane substantially perpendicular to the second axis relative to the second portion when the assembly is supported by the back edge of the blade.
15) A double handle knife comprising:
- a cutting blade with a primary handle;
- said blade having a bottom cutting edge and a back edge with a protruding tang;
- a secondary handle having a least one aperture, wherein the aperture receives the tang thereby providing a double handle knife with a removable secondary handle for cutting operations.
